Abstract

Logic encryption is a hardware security technique that uses extra key inputs to lock a given combinational circuit. A recent study by Subramanyan et al. shows that all existing logic encryption techniques can be successfully attacked. As a countermeasure, SARLock was proposed to enhance the security of existing logic encryptions. In this paper, we reevaluate the security of these approaches. A SAT-based attack called Double DIP is proposed and shown to successfully defeat SARLock-enhanced encryptions.
